This
is a cheap unscreened splitter, intended for ordinary downlead cable.
Our man has managed to force CT167 trunk cable into it. The splitter
was on its back on a flat roof. The lid was on, but there was no
seal on the cable entries. Not surprisingly the cables were full
of water. Each output served about thirty flats. Note the long pieces
of exposed inner, a sure cause of unwanted radiation and pick-up.
